What is a "good" dew point?

Question

On the weather reports they refer to dew point as something having to do with humidity. If it is 85 degrees outside, what is a comfortable (i.e. not too humid) dew point? Similarly what is a comfortable humidity percentage? Thanks.

Answer 1

A very nice dew point for a temp. of 85 would be 70 or below which would make the humidity 54% or below.

Dew point isn't really an indication of how comfortable things are because you need to know the dew point and the temperature to know how good it feels, but humidity is the best indication of how comfortable it is.
>>>To find out your humidity level you must know your temperature and your dewpoint. Or you can simply look at your humidity from internet sources ect.

Relative humidity averaging below 30 percent is to dry and can make it hard to breath after a while.

>>>Relative humidity 40%-55% is very comfortable<<<

Humidity around 60% or above is when the air starts to get sticky and moist.

And 100% is when drops of vapor start to form which is condensation.

The lower the Humidity means the lower the moisture is in the air. High Humidity and High temps. make it feel very sticky and bad outside.

The dew point is the temperature to which the air must be cooled before it becomes saturated and water must condense out. The closer the temperature and the dew point, the more humid the air. Most often we meet humidity as "relative humidity" given as a percent - meaning the higher the percent, the closer the temperature and dew point are.

Humidity is a measure of moisture content of air. Relative humidity is a percentage measure of moisture in the air compared to what the air actually is capable of holding at a particular temperature. Dew point is the temperature at or below which dew or liquid water will drop out of the air because the cooling temperature means the air can hold less water and the relative humidity has reached/exceeded 100% for that temperature and air mass. The heat index takes the temperature and does a correction designed to predict what a human body would interpret the temperature as, meaning, it is a measure of a person's apparent comfort considering temperature and humidity. Simply put, if a person normally becomes a bit uncomfortable in dry heat at 80 degrees, they might notice they feel less comfortable at 70 degrees with certain amount of humidity in the air. As the temperature and/or the humidity increase, the discomfort level increases.

Answer 2

I personnaly think any dew point below 60 F is comfortable, anything above 65 is humid, and anything above 70 is oppressive. I've lived in southern New England almost all my life, folks from other parts of the country/world may disagree. I ignore the percent humidity (also called relative humidity), since it is so dependent on the air temperature, but again that may be a result of where I live - the forcasters talk more about dew point than relative humidity around here.

Answer 3

Good dew point varies with temperature. Ideally, humidity should be measured in absolute humidity, not relative humidity. The relative humidity of 100% at 40 degrees Fahrenheit is the ideal comfort level at most temperatures above 40 degrees. So at 85 degrees Fahrenheit, the most comfortable humidity would be 21%

Answer 4

Sorry i live in canada next time can u put it in degerees.
a comfortable humidity percentae is about 70% or 60% percent
